Screen truns blank after fullscreen

I've got some issues

after watching a video on youtube (or jwplayer) on fullscreen I have to pause the video to possibly avoid getting a blank screen, usually after that happens I press Ctrl+Alt+F1 and log in and input the command

Code:

unity restart

and then after pressing Ctrl + Alt + F7 evrything gets back to normal, but I would rather like to Press ESC and listen to the ending music in the background after watching a movie/video, so I am asking if it's possible to arrange that?

I don't suspend my pc ever. I've updated the kernel, thinking it might help, but...no, still the same, and I've encountered another thing: my mic isn't responding, on windows it's working just fine, but on ubuntu it is useless... my system is falling apart and I don't know what to do
